FILM-DEVELOPING HOLDER.

Application filed April 7, 1925.

My invention relates to improvements in means for holding films during the process of development, and is particularly adapted for use in connection with the development of X-ray films.

At present the only other device I know of for this purpose is a metal holder Which comprises a bar of metal, with a curved projection to engage the side of the developing tank. Riveted and soldered to the bar is a series of spring clips. Each film to be developed is grasped near its edge by one of these clips. This device has many objectionable features. Among them is that the film is indented or perforated at its point of seizure, and, aside from the disadvantage of mutilating the film by puncturing it, there is danger of an operator engaging a part of the/exposed section of the film with the clip. Furthermore; as the film is held only at one point, it immediately curls on immersion in the developing fluid, and, before it can be examined properly, must be dried and then straightened out by insertion in a mount of some kind. Another disadvantage of this holder is that the springs in time become weak, and it is very common to havefilms work loose and sink to the bottom of the tank, where they are located by sense of touch, and rescued .with the very imminent attendant risk of the soft surface emulsion being scratched or injured beyond recognition. Again, the clips become loose not only from use, but also because the developing fluid gradually eats away the solder, for which it has an affinity, consequently weakening the rivets. v

Among the objects of iny invention is the provision of a holder in which no. soldering or rivets are used, which will not affect or be affected by the developing liquid, which will hold the films during immersion firmly and without mutilating them, and in such a way that they can not curl.

Another object of the invention is a holder in which the films may be developed. fixed, washed and dried, in a flat position. and he examined at all times, even while in a wet condition: and one that can be used in connection with a tray as well as a'tank.

Another object is a holder in which the films may be placed in the position and order in which they were taken, before being developed, so as to be ready for diagnosis as soon as the developing is completed.

Serial No. 21,267.

Other objects and advantages will appear from the following description, taken in connection with the accompanying drawings forming part hereof, and in which similar numerals of reference refer to corresponding parts.

Figure 1 is a front elevation of one form of my holder, with receptacles for twelve films; Fig. 2 is a side view of the same; Fig. 3 is a rear view of a holder with receptacles for two films; Fig. 4 is a front view of another form of my holder; Fig. 5 is a similar view showing three separate film holders inserted in it; Figs. 6, 7, 8, 9 and 10 are individual film holders with variously arranged openings; Figs. 11, 12 and 13 are detail views.

Referring to the drawings, and particularly to Figs. 1, 2 and 3, l designates a form of my holder'having twelve receptacles, 2, for the reception of films. One end of the holder is provided 'with a hook, 3, by which it is suspended from the edge of the developing tank. The open end of each one of the receptacles 2 has its corners upturned as shown clearly at 4 in the enlarged sectional view in Fig. 13, to facilitate the insertion of the film. Fig. 3 illustrates a rear view of a smaller holder of this kind, and shows the fastening means for attaching the parts of the holder together as explained below.

. Referring to Figs. 4 to 10 inclusive, 5 indicates another form of my holder, with a hook, 3, similar to that shown in the first form described. This holder is provided with three compartments, 6. 6, 6, which are separated by cross-bars 7, and with depressed portions 8, the latter serving as guides and means for holding separate film holders in place. In Fig. 5 three separate film holders are shown mounted in the main hol'der.

In Figs. 5, tofllfi inclusive, I ha e shown individual film holders with their openings arranged vertically and horizontally and in combination. The vertical openings are numbered 9 and the horizontal openings 10, for the reason explained hereinafter.

Each one of these openings is surrounded. by a gnideway on three of its sides, against which the film abuts when in position, as shown in Fig. 6, the upturned corners, 4, which are a feature of all the individual film holders as well as of the form shown in Figs. 1 to 3, facilitating the insertion of the film through the open end. Each of the ine en heet e eqy e i diridual holdersis also proyided with a hole by iieh,'through the medium of the detachable hook 11, it may depend from the side of the developing tank or be placed in and removed from the developing tray.

The construction of my holder or han er is of great importance as it is designed to avoid the use of solder or the e riveting. It is constructed of metal, preferably of Monel or any other non-oxidizahle metal. lts parts are stamped out i n theusual Way, and the individual holdeisare providediyith smallholes 1 2, and the part l3, fol-min the guideways surrounding three sides lof the openings 9 and 10,'fu'riiished withprojections or eerslt Eig. l1 .These ears .are inserted throughf slots corresppndi g ,t erewith and turnecl over, thus holding the vtypo pans -permanently together, as shown 1n Fi 51 2x 31 2=: I
